Provided is a novel runway embedded-type flash light device in which the light intensity can be changed, and that is lightweight, has a long life, high effective light intensity and small power consumption, and can be placed on the ground with the bottom part facing down without requiring a base, etc. This runway embedded-type flash light device (1) comprises a cylindrical body (10), a ceiling member (11), a light guide member (12), an LED flash light source (13), and a bottom lid member (16). The cylindrical body (10) is capable of being embedded in a runway. In cases where the cylindrical body (10) is embedded in a runway, the ceiling member (11) is arranged in an upper opening of the cylindrical body (10) in a state capable of being exposed on the runway surface. The ceiling member (11) is provided with a flash light emission window. The light guide member (12) is arranged in the flash light emission window. The LED flash light source (13) is arranged inside the cylindrical body (10) in a state capable of emitting a flash light toward the light guide member (12) arranged in the flash light emission window. The flash light emitted from the LED flash light source (13) can be emitted by the light guide member (12) from the flash light emission window toward the outside. The bottom lid member (16) is arranged in a state capable of closing a lower opening of the cylindrical body (10). The bottom lid member (16) includes a support part (17) on an outer surface of the bottom lid member (16) on the opposite side from the cylindrical body (10) side, the support part projecting from the outer surface.
